Drevaniz

Drevaniz is the combination of Russian: древо "drevo" and Permyak: низь "niz'", means "tree sable".

Suminia was slender, lightweight, and designed for climbing. The head is a small skull with huge eye sockets and strong jaws; the teeth are leaf-shaped with serrated edges, ideal for slicing plant material; and the forelimbs and hindlimbs are long, with gripping fingers and opposable-like digits. The posture is semi-erect; they can climb trees with agility, the tail is long and flexible — utilized for balance while climbing, and their skin seems scaly or leathery (fur emerged later in therapsids). However, many arboreal vertebrates share similar physical mechanisms (grasping, clinging, hooking).

Suminia belong to the monophyly/infraorder Venyukovioidea, a sub clade of basal anomodonts.

Suminia was a pioneer climber who combined agility, herbivory, and warm-blooded characteristics – an early attempt in the evolution of mammal-like lifestyles. Suminia possessed large eye sockets, indicating high depth perception, which is important for crossing forest canopies. This species is possibly warm-blooded or semi-endothermic, indicating the evolution of mammal-like metabolism.

Suminia occupied a niche comparable to current squirrels or tree-dwelling herbivores. They ate soft leaves, shoots, and stems high in trees that few other creatures could reach. Suminia was hunted by terrestrial predators including gorgonopsids (saber-toothed Permian carnivores).

Suminia is a herbivore that eats tender leaves, seed fern fronds, early conifer shoots, and possibly fruits or sporangia of tree ferns. Adaptations to arboreal lifestyle are understood to evolve through convergent evolution. However, many arboreal vertebrates share similar physical mechanisms (grasping, clinging, hooking).

Suminia is referred to as the earliest known arboreal tetrapod due to the suggested grasping abilities inferred from the notably enlarged and phalangiform carpal 1 and tarsal 1 which indicate that they possess a divergent first digit, capable of grasping. In combination with a masticatory architecture similar to Dicynodonts (defined by sliding jaw articulation). Suminia's canineless, large leaf shaped teeth follow occluding dentition that is completely marginal which differs from other species with leaf-shaped teeth present. This provides indications not only for herbivory, but into the mechanisms of oral processing. 

Suminia is passive and runs away or climbing up to the trees. Suminia's usual day likely included climbing branches in search of soft plant material, grooming or sleeping in shaded canopies, watching for predators below, and occasionally descending to drink or move between trees.

Suminia is most likely diurnal (active during the day), and it uses eyesight for climbing and foraging. Suminia is an agile climber, relying on her grabbing arms and tail to stay stable among trees.

Their social life may have been similar to that of current tree herbivores, with small family groups or pairs living together. Suminia may defend small feeding territory under treetops. This species avoided danger by climbing or hiding in foliage rather than running. The primary mode of reproduction is most likely egg-laying (oviparous), as seen in most early amniotes, with little or no parental care.

Its fossil localities are primarily derived from the Kotel’nich locality of the Kirov region in Russia. However, there have been some isolated specimen found in a few different localities, all from eastern European regions of Russia. Suminia getmanovi provides anatomical evidence that it lived among the trees, stamping a significant mark in evolutionary history for arboreal lifestyle.
